2018-10-22submodule.c: remove some of the_repository referencesLibravatar Nguyễn Thái Ngọc Duy1-25/+32
Commit 174d131fc9 (submodule.c: remove implicit dependency on the_index - 2018-09-21) makes collect_changed_submodules() take a "struct index_state *" as argument even if it's not really used. My bad. Instead of deleting this argument and fixing up all call sites. Let's take this opportunity to remove some the_repository instead because there's one or two in this function (and two more in its callback). The callers can also get rid of some the_repository.

2018-10-09submodule: add a helper to check if it is safe to write to .gitmodulesLibravatar Antonio Ospite1-0/+18
Introduce a helper function named is_writing_gitmodules_ok() to verify that the .gitmodules file is safe to write. The function name follows the scheme of is_staging_gitmodules_ok(). The two symbolic constants GITMODULES_INDEX and GITMODULES_HEAD are used to get help from the C preprocessor in preventing typos, especially for future users. This is in preparation for a future change which teaches git how to read .gitmodules from the index or from the current branch if the file is not available in the working tree. The rationale behind the check is that writing to .gitmodules requires the file to be present in the working tree, unless a brand new .gitmodules is being created (in which case the .gitmodules file would not exist at all: neither in the working tree nor in the index or in the current branch). Expose the functionality also via a "submodule-helper config --check-writeable" command, as git scripts may want to perform the check before modifying submodules configuration.

2018-10-09submodule: factor out a config_set_in_gitmodules_file_gently functionLibravatar Antonio Ospite1-7/+3
Introduce a new config_set_in_gitmodules_file_gently() function to write config values to the .gitmodules file. This is in preparation for a future change which will use the function to write to the .gitmodules file in a more controlled way instead of using "git config -f .gitmodules". The purpose of the change is mainly to centralize the code that writes to the .gitmodules file to avoid some duplication. The naming follows git_config_set_in_file_gently() but the git_ prefix is removed to communicate that this is not a generic git-config API.

2018-09-28rev-parse: --show-superproject-working-tree should work during a mergeLibravatar Sam McKelvie1-1/+1
Invoking 'git rev-parse --show-superproject-working-tree' exits with "fatal: BUG: returned path string doesn't match cwd?" when the superproject has an unmerged entry for the current submodule, instead of displaying the superproject's working tree. The problem is due to the fact that when a merge of the submodule reference is in progress, "git ls-files --stage —full-name <submodule-relative-path>” returns three seperate entries for the submodule (one for each stage) rather than a single entry; e.g., $ git ls-files --stage --full-name submodule-child-test 160000 dbbd2766fa330fa741ea59bb38689fcc2d283ac5 1 submodule-child-test 160000 f174d1dbfe863a59692c3bdae730a36f2a788c51 2 submodule-child-test 160000 e6178f3a58b958543952e12824aa2106d560f21d 3 submodule-child-test The code in get_superproject_working_tree() expected exactly one entry to be returned; this patch makes it use the first entry if multiple entries are returned.

2018-09-07Revert "Merge branch 'sb/submodule-core-worktree'"Libravatar Jonathan Nieder1-14/+0
This reverts commit 7e25437d35a70791b345872af202eabfb3e1a8bc, reversing changes made to 00624d608cc69bd62801c93e74d1ea7a7ddd6598. v2.19.0-rc0~165^2~1 (submodule: ensure core.worktree is set after update, 2018-06-18) assumes an "absorbed" submodule layout, where the submodule's Git directory is in the superproject's .git/modules/ directory and .git in the submodule worktree is a .git file pointing there. In particular, it uses $GIT_DIR/modules/$name to find the submodule to find out whether it already has core.worktree set, and it uses connect_work_tree_and_git_dir if not, resulting in fatal: could not open sub/.git for writing The context behind that patch: v2.19.0-rc0~165^2~2 (submodule: unset core.worktree if no working tree is present, 2018-06-12) unsets core.worktree when running commands like "git checkout --recurse-submodules" to switch to a branch without the submodule. If a user then uses "git checkout --no-recurse-submodules" to switch back to a branch with the submodule and runs "git submodule update", this patch is needed to ensure that commands using the submodule directly are aware of the path to the worktree. It is late in the release cycle, so revert the whole 3-patch series. We can try again later for 2.20.

2018-08-29convert "oidcmp() == 0" to oideq()Libravatar Jeff King1-1/+1
Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

2018-06-14submodule: unset core.worktree if no working tree is presentLibravatar Stefan Beller1-0/+14
When a submodules work tree is removed, we should unset its core.worktree setting as the worktree is no longer present. This is not just in line with the conceptual view of submodules, but it fixes an inconvenience for looking at submodules that are not checked out: git clone --recurse-submodules git://github.com/git/git && cd git && git checkout --recurse-submodules v2.13.0 git -C .git/modules/sha1collisiondetection log fatal: cannot chdir to '../../../sha1collisiondetection': \ No such file or directory With this patch applied, the final call to git log works instead of dying in its setup, as the checkout will unset the core.worktree setting such that following log will be run in a bare repository. This patch covers all commands that are in the unpack machinery, i.e. checkout, read-tree, reset. A follow up patch will address "git submodule deinit", which will also make use of the new function submodule_unset_core_worktree(), which is why we expose it in this patch.

2018-06-14submodule: fix NULL correctness in renamed broken submodulesLibravatar Stefan Beller1-2/+4
When fetching with recursing into submodules, the fetch logic inspects the superproject which submodules actually need to be fetched. This is tricky for submodules that were renamed in the fetched range of commits. This was implemented in c68f8375760 (implement fetching of moved submodules, 2017-10-16), and this patch fixes a mistake in the logic there. When the warning is printed, the `name` might be NULL as default_name_or_path can return NULL, so fix the warning to use the path as obtained from the diff machinery, as that is not NULL. While at it, make sure we only attempt to load the submodule if a git directory of the submodule is found as default_name_or_path will return NULL in case the git directory cannot be found. Note that passing NULL to submodule_from_name is just a semantic error, as submodule_from_name accepts NULL as a value, but then the return value is not the submodule that was asked for, but some arbitrary other submodule. (Cf. 'config_from' in submodule-config.c: "If any parameter except the cache is a NULL pointer just return the first submodule. Can be used to check whether there are any submodules parsed.")

In a later patch we want to improve submodule merging by using the output() function in merge-recursive.c for submodule merges to deliver a consistent UI to users. To do so we could either make the output() function globally available so we can use it in submodule.c#merge_submodule(), or we could integrate the submodule merging into the merging code. Choose the later as we generally want to move submodules closer into the core. Therefore we move any function related to merging submodules (merge_submodule(), find_first_merges() and print_commit) to merge-recursive.c. We'll keep add_submodule_odb() in submodule.c as it is used by other submodule functions. While at it, add a TODO note that we do not really like the function add_submodule_odb().

2018-04-26cache.h: add repository argument to oid_object_infoLibravatar Stefan Beller1-1/+1
Add a repository argument to allow the callers of oid_object_info to be more specific about which repository to handle. This is a small mechanical change; it doesn't change the implementation to handle repositories other than the_repository yet. As with the previous commits, use a macro to catch callers passing a repository other than the_repository at compile time.

2018-03-29submodule: fixup nested submodules after moving the submoduleLibravatar Stefan Beller1-3/+3
connect_work_tree_and_git_dir is used to connect a submodule worktree with its git directory and vice versa after events that require a reconnection such as moving around the working tree. As submodules can have nested submodules themselves, we'd also want to fix the nested submodules when asked to. Add an option to recurse into the nested submodules and connect them as well. As submodules are identified by their name (which determines their git directory in relation to their superproject's git directory) internally and by their path in the working tree of the superproject, we need to make sure that the mapping of name <-> path is kept intact. We can do that in the git-mv command by writing out the gitmodules file first and then forcing a reload of the submodule config machinery.

2018-03-29submodule-config: remove submodule_from_cacheLibravatar Stefan Beller1-2/+2
This continues the story of bf12fcdf5e (submodule-config: store the_submodule_cache in the_repository, 2017-06-22). The previous patch taught submodule_from_path to take a repository into account, such that submodule_from_{path, cache} are the same now. Remove submodule_from_cache, migrating all its callers to submodule_from_path.

When using hard reset or forced checkout with the option to recurse into submodules, the submodules need to be reset, too. It turns out that we need to omit the duplicate old argument to read-tree in all forced cases to omit the 2 way merge and use the more assertive behavior of reading the specific new tree into the index and updating the working tree.
